Hi mate,
I have installed the phone box with signal amplifier and antenna, wiring done as per Elsa, but I am not sure it is working or not,
Could you please tell me where we have to change in coding!!!

I used the coding dongle from Kufatec, and i would say that it set these bits:
If you leave the phone on the charging mat for an hour, the phone will get pretty hot - meaning that it is charging.

In that case, i would uncheck bits 0 and 5 and check bit 1.
The antenna coupling connections look right.
I don't know how to check if your phone is connected to the external antennas - sorry.

Hi mate,
Please see the attached picture, which shows the opposite of connection,Black connector is connected to Antenna ,
Confused now,
As per kufatech,Could you please tell me black connector goes to phone box and claret violet goes to External Antenna, is it correct ?

If I wanted to install it as "phone box Light", meaning without any wiring to aerial, what are the minimum steps in terms of wiring, to ensure the MMI sees it as original equipment?
I would make a single wiring harness.
The black 6 pin connector to the charging pad is called T6bt
Pin 1 goes to fuse SC2 in the left side of the dash (at least on a LHD car) Or you could just take this on the navigation unit
Pin 2 goes to pin 5 in the gray connector T12n in the Quadlock to the navigation unit
Pin 3 goes to pin 11 in the gray connector T12n in the Quadlock to the navigation unit
Pin 4 is ground
That should do it.....

Thanks a lot, that's really helpful. I am really a n00b, so I would need to find the courage to do such electrics work on the car. Which one of those 4 is power?How does the qi get the necessary power?
I have seen some cheap copies on ali but it looks like they simply hijack the cigarette lighter for independent power and no other cables are involved? I suppose those would have no communication with the MMI whatsoever (for charging/forgetting notifications)?

Hey @strandgaard , sorry to bug you with my noob questions. I have some trouble finding the t6bt connector on the internet. All my searches bring nothing back. Do you happen to know a good link from where to buy it? Also, what kind of wire is advised for the harness? Specific gauge, etch?
No problem.
But i am not much help this time.
I bought my wiring loom from Kufatec in Germany, and the connector is part of that loom. The wires are 0,35 square mm's - don't know how much that is in gauge.
See your local Audi dealer and have them look it up in the spare parts catalogue.

I just had a second look.
The connector is 4B0971978B and the corresponding pins (2 pins with with 0,5 m wire in between) are numbered 000979009E

Thanks a lot, you are awesome! I think based on all the valuable info you have shared, I will collect all the electrics/parts required from ebay/ali/whatever and have a go at it myself, as the local car electricians really hesitate to tell me if this is doable(doubt they have ever done it). Since I am interested in the "phonebox light" implementation with just the 4 wires for charging/notification, I think it would be a shame paying Kufatec 110 euros for the wiring loom. Although I assume the instructions manual came in very handy....?
One last thing, did you use a "piggyback" fuse cable and added it to the phone fuse input(SC2)?

That's great. I thought that specific position was not empty, that's why I asked about the piggyback. Doesn't the smartphone interface use that plug? It says "telephone".
SC2 can supply different contri
ollers beside "J1146 Charging unit 1 for mobile devices" - could be J676 chip card reader, R215 external multimedia unit, R126 Telephone bracket. If you have either of these, it will be occupied. I would solder the wire to the fused wire on the back of the fuse holder.
R199 - Connection for external audio sources (Smartphone interface) is SC5
But they are all fixed 12V so you can use any vacant position.

Perfect. Thanks again. I will open the box and act according to whether it is occupied or not. Wouldn't it be better to use a piggyback so that an actual fuse can be connected for a proper circuit-breaker?That's if it is possible to pass the cable to the front(facing) side of the fuse box....
Hey @strandgaard , is there by chance any "official" document where this specific wiring you mentioned is shown? I just want to make sure I have the correct information, as I have now collected all the materials and planning to go ahead with it soon. Thanks.
There is an official wiring diagram for sale (7 euro) at erwin.audi.com
And when i checked, i found a small error in my previous description. It should be:
From the black 6 pin connector
Pin 1 (+12V) goes to fuse SC2 in the left side of the dash (at least on a LHD car) Or you could just take this on the navigation unit
Pin 2 (Can - L) goes to pin 7 in the gray connector T12n in the Quadlock to the navigation unit
Pin 3 (Can - H) goes to pin 1 in the gray connector T12n in the Quadlock to the navigation unit
Pin 4 is ground

Thanks a lot for spending the time to go have a second look at it. I really appreciate the updated information.
Considering that the quadlocks are notorious for having very short leash/give, do you have any tips for getting enough space to work on the quadlock?

You need to remove the glove compartment and navi unit. That gives you plenty of give.
Unfortunately I am not seeing a link for PMing you on your profile page. Please feel free to do so if you can see it on mine
Is there a picture of the T12n pin numbers? I just want to make sure I've got the correct ones. But in any case, 1 &7 should be on a edge side and on mine both edges are filled with pins.
Could it be that because I already have the smartphone interface which charges the phone, those pins go there and take up the spot?
I am looking for help too.
I just need part numbers and advice
I have
8w0864981
but looking at Kufatec listing there is also cables we need, an amplifier and maybe even a different aerial?
Any list of full part numbers would be great. so i can find them for as cheap as possible then locate someone who can just charge labour for fitting.

managed to get hold of the actual wireless charging box completely.
Will now just purchase separate wiring kit from Kufatec for 100 euros.
Any one local to Dorset or London who is able to fit this?
Most places are supply and fit unfortunately.
Also, if its on the wireless charging pad and amplifying signal, can I also use apple carplay via the wire at the same time?
Yes - you can use wireless charging and carplay at the same time - although I would imagine, that the phone charges over the cable connection instead.
My retrofit started working out of the blue 6 months later. I have no explanation, it just did, without me touching anything. Probably the fact that I chose to make my own wiring harness and buy used original chargers(instead of going for the brand new OE Kufatec kit), had to play a role on this random experience. What is certain is that the instructions for wiring and coding available to the public, are 100% correct.
